APC (green) connectors are polished at an 8° angle, pushing return loss above 60 dB. APC is required for GPON, RF-over-glass, and any link sensitive to back-reflection. Never mate APC to UPC — the air gap causes high loss and can damage end-faces.\u003c\/p\u003e\u003ch4\u003eAre these patch cables tested before shipping?\u003c\/h4\u003e\u003cp\u003eYes.
